This drive isof special interest as showing the extent to which individual. Garbe. This engine, with only 963 sq. ft. of heating surface,gave higher speed than the first two, which were specially de-signed and built for the trials. Its speed with six cars miles per hour, and with three cars miles per horse-power developed approximated 2,000. The fourth locomotive, which headed the list for speed, is thedesign of Mr. Wittfield, of the Prussian State Railways, andthe cab in front, and is to be exhibited at St. Louis. Both en-was built by Henschell & Sons, of Cassel. It is arranged withgine and tender are encased in a sheathing of steel, giving asmooth exterior surface to reduce the wind friction. This is a4 4-4 type 4-cylinder balanced compaund. It has 2,766 of heating surface and weighs tons. This engine gavea speed of miles per hour with six cars, and mileswith three cars.
